IDOM carried out the supervision of all works developed during the execution of the decommissioning and closure plan of CN José Cabrera related to the commissioning of the necessary fire protection and HVAC systems. The plan was divided into two specific areas: the first one was a conventional area comprising all the buildings and installations which did not contain any radioactive elements whereas the second one included all the areas containing radioactive materials (Reactor Building, Auxiliary Building, Gas Treatment Building and Warehouses with Irradiated Materials).
